Application filed September 20, 1921. Serial No. 501,880.

To all whom it mwy concern: 7

Be it known that I, .FEN ICK .F. SAXE, a citizen of the United States, residing at New York city, in the county of Bronx and State of New York, have invented new and useful Improvements in Window Cleaners,

- pressed rod 22 carrying at its end a cleaningof which the following is a specification.

This invention relates to window cleaners and particularly to mechanical means connecting interior and exterior cleaning devices so that the operation of one will effect the simultaneous and corresponding operation of the other.

The principal object is to produce a device of this nature which shall be simple of construction, cheap to manufacture, and highly efiicient for the purpose for which it is designed.

Another object is to provide a novel and improved means for connecting and 'operat ing the interior and exterior cleaning devices. a

' With these and other objects in view which will be more apparent as the specification proceeds, the invention resides in certain novel construction and combination and arrangement of parts, the essential-elements of which are hereinafter fully described, are particularly pointed out in the appended claims and are illustrated in the accompanying drawing, in which Figure 1 is an interior elevation of my improved cleaning device.

Figure 2 is a vertical sectional View of the same. v I Figure 3 is a detail perspective view of the connecting joint.

Referring to the drawing in detail, 10 represents a frame which may be made of cast metal or othersuitable material and which is provided with interior and exterior uptively and is formed at its base with grooves 13 and 14 whereby the frame 10 may be clamped to the stop of the window frame either in position tq receive the upper sash or to receive the lower sash. In cases where the bottom of the window frame is not provided with an upwardly extending stop, suitable cleat of wood or other desired material may be secured .to the window frame as a substitute for the stop.

Mounted for rotation in suitable bearings in the upper ends of arms 11 and 12 are stub shafts 15 and 16 carrying at one end a gear wheel 17 and at the other sprockets ends.

any

18. Mounted on the shafts 15 and 16 soas to enclose the gear wheels 17 are housings 19 which also hold rods 20 formed with racks 21, so that said racks engage the respective gears 18. Mounted at the outer end of each member 20 is a horizontal spring member 23 the cleaning members being pressed toward the window glass by means square openings in bosses at the ends of the members 21. The sprockets 18 are connected by chains or belts 26 with lower.

sprockets 27 and 28 mounted von'the ends of a shaft 29 having its bearings in the frame 10. A guide member 30 is mounted on trunnion bearings in the frame 10 and is provided with upwardly extending arms 31 havingguide members 32 at their'upper as described and as shown at 30 the trunnions mounted in the frame 10, 1t follows that said frame 30 compensates for move- Connecting rods 331-are. secured to a ments of the. connecting rods 33 on rotation;

of the crankshaft 34.

In .operation the lower window sash is thrown up, then the frame 10 is secured to the window stop either at the groove 13 or the groove 14 according to whether it is the upper or lower window thatis to be cleaned.

The cleaning members 23 are provided with I suitable clothes orls'ponges and are separated, after which the window sash-is pulled down and the members 23 are released so that they are pressed against the window by their springs 24. The operator nowgrasps the knob 25 and moves the innercleanmg member. 23 over the innerv surface of thr window. The movement of the member. 20 in the sheath 19 be communicated to I i 65 l of springs 24. -Mounted on the member 20 the smaller exterior parts by means of the gears, sprockets and belts; and any rotary movement of the inner member 19 on the pivot 15 will be communicated to the outer member 19 by means of the crank rods 33 and crank shaft 34:. This is because pins 35 are below the centers 15 and 16 and When the inner member 19 is rotated about center 15, its pin 35 will cause inner rod 33 to effect such rotation of shaft at as will through outer rod 33 and its pin 35 effect the same rotation of the outer member 19 about its center 16. i

. What is claimed as new is 1. In a device of the class described, the combination of a pair of cleaning pads, ma-

nipulating rods formed on each of said pads,-

means on said rods for forcing the pads toward each other, gear racks connected to each of said rods, a gear meshing with each of said racks, a sprocket operable by each v of said gear-s, means whereby 'movement'may be communicated from one of said sprockets to the other of said sprockets, and supporting means for the aforesaid mechanism.-

2. In a device of the class described, the combination of a pair of cleaning pads, manipulating rods formed on each of said pads, means on said rods for forcing the pads toward eachother, gear racks" connectedto each of said'rods, a gear'meshing with each of said racks, a sprocket operable by each of said gears, means whereby movement may be communicated from one of said sprockets to the other of said sporckets, a sheath for 1 each of said rack bars, connecting .rods having one end' connected to each of said sheaths and the other end to a crank shaft, support-ing means for the aforesaid mechanism as and for the purpose specified.
